Abstract :
Potash alum, a double salt composed of
potassium sulfate and aluminum sulfate, has long been
recognized for its utility in various industrial applications,
notably in water treatment, food processing, and medicine.
This paper explores the synthesis, characterization, and
diverse applications of potash alum, with particular
emphasis on its role as a coagulant in wastewater
treatment. The synthesis of potash alum, utilizing a double
decomposition reaction, is examined, and the resulting
product is characterized through solubility, pH
measurements, and thermal analysis. The study also
investigates the coagulation mechanism of potash alum in
water treatment, highlighting its effectiveness in removing
suspended solids and improving water clarity. The
findings emphasize the environmental and economic
advantages of using potash alum, while addressing
limitations such as pH sensitivity and residual aluminum
content in treated water.
